Method Detail

downcast

public MSSQLConnectOptions downcast(SqlConnectOptions connectOptions)

Description copied from interface: Driver

Downcast the connect options to the specific driver options.

Specified by:

downcast in interface Driver<MSSQLConnectOptions>

Parameters:

connectOptions - the options to downcast

Returns:

the downcasted options

newPool

public Pool newPool(Vertx vertx,
                    java.util.function.Supplier<Future<MSSQLConnectOptions>> databases,
                    PoolOptions options,
                    NetClientOptions transportOptions,
                    Handler<SqlConnection> connectHandler,
                    io.vertx.core.internal.CloseFuture closeFuture)

Description copied from interface: Driver

Create a connection pool to the database configured with the given connectOptions and poolOptions.

This method is not meant to be used directly by users, instead they should use Driver.createPool(Vertx, Supplier, PoolOptions, NetClientOptions, Handler).

Specified by:

newPool in interface Driver<MSSQLConnectOptions>

Parameters:

vertx - the Vertx instance to be used with the connection pool

databases - the list of databases

options - the options for creating the pool

transportOptions - the options to configure the TCP client

connectHandler - the connect handler

closeFuture - the close future

Returns:

the connection pool

createConnectionFactory

public ConnectionFactory<MSSQLConnectOptions> createConnectionFactory(Vertx vertx,
                                                                      NetClientOptions transportOptions)

Description copied from interface: Driver

Create a connection factory to the given database.

Specified by:

createConnectionFactory in interface Driver<MSSQLConnectOptions>

Parameters:

vertx - the Vertx instance

transportOptions - the options to configure the TCP client

Returns:

the connection factory

parseConnectionUri

public MSSQLConnectOptions parseConnectionUri(String uri)

Specified by:

parseConnectionUri in interface Driver<MSSQLConnectOptions>

Returns:

true if the driver accepts the connectOptions, false otherwise

acceptsOptions

public boolean acceptsOptions(SqlConnectOptions options)

Specified by:

acceptsOptions in interface Driver<MSSQLConnectOptions>

Returns:

true if the driver accepts the connectOptions, false otherwise

appendQueryPlaceholder

public int appendQueryPlaceholder(StringBuilder queryBuilder,
                                  int index,
                                  int current)

Description copied from interface: Driver

Append a parameter placeholder in the query.

The index starts at 0.

• When index == current indicates it is a new parameter and therefore the same * value should be returned.
• When index < current indicates the builder wants to reuse a parameter. The implementation can either return the same value to indicate the parameter can be reused or return the next index to use (which is shall be the current value

Specified by:

appendQueryPlaceholder in interface Driver<MSSQLConnectOptions>

Parameters:

queryBuilder - the builder to append to

index - the parameter placeholder index

Returns:

the index at which the parameter placeholder could be added

wrapConnection

public io.vertx.sqlclient.internal.SqlConnectionInternal wrapConnection(io.vertx.core.internal.ContextInternal context,
                                                                        ConnectionFactory<MSSQLConnectOptions> factory,
                                                                        io.vertx.sqlclient.internal.Connection conn)

Specified by:

wrapConnection in interface Driver<MSSQLConnectOptions>
